Problems with Xen server

Had to move an old server that hosts some virtual machines. I can't get them back up. The config files are as so:

    # Configuration file for the Xen instance vpn.linux.core.theimaginariumstudios.com, created
# by xen-tools 4.2 on Mon Jul  2 20:09:54 2012.
#

#
#  Kernel + memory size
#
kernel      = '/boot/vmlinuz-2.6.32-5-xen-amd64'
ramdisk     = '/boot/initrd.img-2.6.32-5-xen-amd64'

vcpus       = '1'
memory      = '512'

#
#  Disk device(s).
#
root        = '/dev/xvda2 ro'
disk        = [
                  'phy:/dev/drbd2,xvda2,w',
              ]


#
#  Physical volumes
#


#
#  Hostname
#
name        = 'lic1-linux'

#
#  Networking
#
vif         = [ 'ip=192.168.11.231,mac=00:16:3E:52:87:24' ]

#
#  Behaviour
#
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'

When I start the VM, the root disk isn't detected - /dev/xvda2. I'm not sure where this is, could it be a link to another disk?

drbd2 exists however. I've re-retried and one of the VMs worked and could detect xvda2, but others are still having issues. I used the xm create -c command to launch it

I get this message when launching the VM:

done.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
